The staple -isoperatiom. formed atthe nQse, lof the armv-Q. with its 1 legs or pointsupstanding, and is .'driven -from the place it. is formed by the driver-upward into the work. -The staples` are formed from staple wire 4which-.is drawn from a suitable reel 6.'

As shown in F'ig. 5 the staple wire 4: is

- fed upward through a guide tube 7 through l tive machine the stapleis' formed. at thev v.nose of the machineanddriven from that .3 3 pointinto the'work. Thisis. particularly.

'formed to receivethe wire. of the-staple wire 4 when fed to position.

The wireis then severedbycoaction oicutting edges 11 and 12 formed respectively on the -underside of-the movable. former 13 and the upper ledge. of bearing 8 (seeFig. 11).' Immediately. followingA the severing operation the' -severedend of the wire is bent atright angles beneath the loop bar 9 by theformer 13 moving to the leftas shown inFig. 7. The' former 13 is thenmoved 'upward by a lifter 14 b endin the wire'upward about the loopforming the other leg of the- 'bar 9 van staple. The driver 5 then risesforcing the movable loopbar 9 out of line `through-the action of acam.1ug 15 (seeFigsJ12, 13 and la), and drives the'staple upward into'the work.

Thus, it wn'l be noted thatin the illustraadvantageous in that iteliminates the' necessity of transferring the staple.lv from. vtheplacewhere itis formed to .the pl'ace where it is driven. y

.As'shown in Fig. 10 the former 13 re. ciprocates horizontally between-arms 16 and 17 'of the lifter-14,- arm '17 being so 'constructedgas'toaccommodate the rearward-throw' of the former 13. The `former isprovided with a groove 18 (see Fig. 16) 'to receive and guide'the-staple legwhen theffo'rmerl'l?, is

moved horizontally and verticallyl tocomplete the formation 'of the,staple. '1t -willv be noted thatl the former 13 first is moved-ihorizontally from the nose of the machine thereby 'cutting the wireand` bending it at right angles, and then is moved lvertically i formingthe second leg of thestaple about 'the loop `bar 9.` As shown -in Fig.11 `the cutting edge' 11.v of the former 13 is formed at an angle ofapproximately/150'@ the horizontal and` the upper edge 12 4of bearing fguide tube 7, bearing :8,in front of the former 13, and-between loop bar9 and bearing. 10 is drawn from supply reel. 6 by coactin feed andgripping rolls 19 and 20 whic are advanced intermittently by areciprecot- 8 is formed tocooperate therewith, to sever theiwire whenthe former 13 is moved to the-'-'rear 1om the lnose of the .machine Thestaple-wire 4 whichpasses through ing pawl 21 acting upon Memisa carriedbythe wheel-19.A The mechanism describ d' may 4be actuated from the'drivingshaft 23`by' any suitable.` .I

means, for example, by the instrumentalities shown `in the drawingswhich .will nowr 4be described.

The staple'wire feed pawl 21- is operated by a lever 21. pivotallyconnected to one end of lever 21", the other end of which is pivoted. tothe frame of the machine at 21c the lever 21b carryinga roller21dcontacting with Cain .-21e .on the'ishaft 23. VThe. roller 21@lisheld against the'c'am 21e by means of spring 21f.

The former 13is reciprocated horizontally through eonnectingrod 13a'having a's'lotted block. 13"v at its rear. end through which the shaft231 passes. The block 13b carries a roller 13c which contacts withacam13d on the shaft 23- through the` action of spring 13". Said spring isso arranged as to quickly return the former 13 to its original position,as shown in Fig. 5, .when the roller 13c passes the projection on thecam136.` Theformer 13 is moved' verticallythr'ough 'the action of thelifter'14.

The lifter 1 4- is operated through the fulcrumed arm 14 connected tothe lifter 14 by a pin andslot connection 14", and carrying a roller 114at its rear-extremity which roller contacts with a cam 14d carried-bytheshaft 23. The-roller 14 is held in contact with the vcamV 14d by meansof spring 14.

Thestapledriver 5 is-ope'rated by'a ful; crumed lever 5a having fitslfrontend con? neeted to the'l staple-'driver by a pin and slotconnection 5", and having its rear end provided witha roller 5c engagedby a cam 5d von the shaft 23, said cam having 'a' projection tooperatethe lever to give the staplel driver a quick up stroke and allow itsprompt` return through spring 5..

As will be understood-,the vcams are' so the action of timed and the'larrangement of the pa'rtsia` the. loop bar 9 to` return to initialposition through the action' of a spring 24, the former 13 is returnedto' initialposition `by the spring 13 andthe s 'taple wire Jeed'mechanism then advancesthe wire t v:tor another staple upward toposition between the loop bar 9 and the bearing 19.

Wh-ich it may loe-lengthen may be desired.- At each rotation of'- the--essaies ing and clinching device to cooperate .with the staple driver iscarried atthe end of arm 3. This device as shown consists of a verticalplunger provided with' a -rack 31 meshing with a segmental gear32pivoted at 33.` The segmental gear 32is provided with an arm 34 t0which is'pivoted a link 35 connected to a cam lever 36 pivotedat 37 andcarrying a roller 38 engag ing a cam 39 car ied byftheshaft 23 saidroller being .heldr' against said cam by, a

driver to' clamp the box head or end dur1n a stapling operation, andtofserve as' an anvl or clincher to oppose the action of the staple'driver and clinch the ends of staples which maybe driven-through thework. The tim-v ing should be such' that the plunger clamps theWork'before the' staple is dr1ven. The

plunger rises andA releases the Work after the-driving of each staple,enabling the operator to move the box on the stapli'ng'arm the requireddistance foridriving the vnext staple. .n

The manner of using the machine, will be clearlyv understood by -thoseskilled in' the art, and-is indicated i'n Figs. 1 and 25 of the drawingsshowing anA ordinary Wirebound box with foldably'connected side andbottom sections provided with cooperating end cleats and heads or'. endsarranged in? side the cleats to be stapled thereto.' ln performing thestapling operation, the end or head board-rests upon the staplingarmasshown in Figure.,7 1, and the operator manipulatesthe boxon said armWhile operating the machine. successively to drive a ron1 of staplesthrough each cle'at; that is to say,

through the head or end board'v along linesA which .cause the staples-to Ypass into the cleats, and in this operation the-tapering nose orterminal of the stapling arm serves as a guide for. enabling theoperator to posi- 'tion the WOTk and t0 gauge the staples from ythe boxsides. 1. f .y

' Power for operating the machine may be applied in 'any' suitablemannen .as for-'in stance, by the power pulley' 45 shown in Figure 2,which may be controllably' clutched to the shaft '23 by any suitableclutch mechanism.

From the foregoing description vit will be understood that onepracticable process em.

-bodying features of this invention comprises the feeding of a wire to adesired staple driving point in such amanner that the end portion of theWire forms one leg of a staple in position to be driven, 'severing thewire a-dis tance from its extremity and' bending the wire to completethe formation of the staple.

'Y '-1. A'machine for .use in at the driving point. Such a process ispar. ticula'rly advantageous for inside box staplingoperations in thatit -permits the forming 'of 'a staple in. aiconlined space, for Yexample, closeto a box side or in a 'box corner. Other advantagesresulting from the described-processwill appear to those skilled in theart. h Obviously .the present invention is not limited to :the specificdetails` of vmechanism aidpro'ceduredescribed above for illustration andit will be understood that it is'n'ot indispensable that all thefeatures of the ined ir-shortened as f-vention'be empioyedgin a singlemachine or process since the featuresrmay be used tol advantage'separately as defined in the subj jined claims.
